Patented Dec. 8, mos.

Application and February 2a, 1908. Serial No. 418,354.

To all whom it may concern:

Be it knownthat I, GUILLERMO J. DE GUIL- S ain, residingat Barcelona, inthe Province 0 Barcelona and Kingdom of Spain, have invented certain newand useful Improvements in Means for Electrical Transmission of De-'signs, Figures, and Photographs; and I do.

. in the manifolder of thesending station and the times apparatus of thereceiving station are substituted by s chronical drums, or in otherwords, that t ey are of the same dimensions and revolve at the samespeed imparted thereto by a clock motion -or other equivalent device ormechanism.

Each drum surface is in contact with a style'and both styles are causedto print on the respective drum a' helical 'line of the same path anddiameter,'i. 0., absolutely identical to one another. This result isobtained either by moving the styles parallel to themselves or by movingthe drums upon their axes.

According to my invention I cover the transmitting or sending drum witha layer or plate of bichromate-gelatin u on which ithas been re roducedand cans to become high-relief t e hoto raph or design comprising thesha es to e transmitted. Any other arrangement under which the reliefrepresents the shadows or shades maybe employed. Furthermore, Iintroduce in the transmitting apparatus several plates or con tacts inelectrical connection with disks tangentially arranged on a roller orbrush inserted in the electrical circuit. The st le is located at theend of a simple or mu tiple lever, the other end of which may rest uponand make contact with one of the plates or it may rest out of contact.

All the disks are rotative; one of them is smooth and the others aretoothed or scratched; each of these is uniformly toothed throughout itscircumference but the teeth 'of one disk are different in number ascompared with. the other disks, so that in a given time each disk makesa number of contacts which .generate a given number of currents orseries of Hertzianwaves and produce on the receiving apparatus points orlines of a given length, more or less separated from the originalrepresented by the relief.

' A further object of my invention is to provide a mechanism to control.the movement ofthe drums of both the transmitting and receivingapparatus; the latter runs with a more accelerated movement than theformer,

but at the end of the revolution it stops, and

by means of an electrical connection it goes on with the same movementwhen the transmitting drum begins the next revolution.

In the accompanying drawings I represent the arrangement of parts andapparatus to carry out my invention or improved method fortelegraphicaltransmission of designs and s photograp Figure 1 is a schematical viewof a sending station and Fig. 2 is a schematical view of a receivingstation, showing the arrangement for transmitting and receiving designsand photographs and. for controlling the, movement of the drums. Fi s;3, 4, 5 and 6, are detailed views of the dis lis cc-c c on a largerscale. Figs. 7 and 8 are front views of the plates for'controlhng themoveent. Fig. 9 is a section on line zz of s- Referring to the sendingstation, Fig. 1,

the revolving drum or cylinder -d is coat-' ed with a layer -h ofbichromate-gelatin or other material, having a high-relief photograph ordesign formed thereon. The styleeach other, which reproduce the shadowsof is lifted or lowered to follow the corrugations or prominentand'depressedparts of the design. The shaft nof the lever -bis connectedto one pole of a battery The lever'b carries at one end asmall rollerr+- to make contact with plates --a-c-a a of conductive material,separated from each other, and circularly arranged under the curved pathof the roller r. On each oi'thesc conductive plates -a-a-c-c is secureda wire -mwith a brush --mwhich terminates on the ried by the shaft g ofebonite (hard rubber) or other isolating material, and turning alltogether at the same speed. One of the disks c Fig. 3 is quite smoothedged while the disks c c -c Figs. 2, 5, 6, are

toothed, but the teeth of each disk are different in number and sha eand are in relation to the length of the fine or point to be printed onthe receiving apparatus. All of these disks are tangential to a metalliccylinder 'i, or brush of any shape which by means of the shaft 'i andwire 6 is placed in the circuit of the battery p.

The receiving station, Fig. 2, comprises also a revolving drum orcylinder d and a style e which works in combination with the movementsof the style e of the sending station and the contacts established bydisks ccc 'c through the coil 10.' The styles e e are movedv parallel tothemselves in res ect of the rotary motion of the cylinders id When rmakes contact with one of rent passes through the respective disks -c -c-c -c each of the disks producing a'flow and interruption of currentsand Hertzian waves, according to the size and shape of the teeth oftheir surface.

The plant shown in Figs. 1 and 2, is intended for wireless telegra hicstations ;.but it may be applied to usua wire telegraplhy, by causingthe wire 5 Fig. 1 and t e wire H Fig. 2, to communicate with the earth.Thus, when the receivingstation re-- ceives the currents orHertzianwaves pro duced by the contact of the disk c, the style e willproduce plain lines which form the black part of the design and when thetransmission takes place throu h disks -c"c c the style wi mark pointsor lines more or less )long and spaced apart, which reproduce thedifferent shadows .or shades of the design corresponding to the patternrelief.

- It is impossible in practice to obtain identical movements for twodifferent ap ratus; certainly there are always small it ferences and theerrors .grow and grow as they accumulate with one another at eachrevolution; In order to prevent these errors being accumulatedduring-the rotation of the e receiving station revolves somewhat quickerthan-the cylinder d at the sendconnected so that d communicates with -dat the beginning of each revolution, and d stops at the end of itsrevolution and does not recommence its rotation until it receives thecommunication from -d-. Under these circumstances, although someerrormay certainly occur at each revolution, these errors are ofidentical value, and do not accumulate, so that a quite synchronicalmotion is produced.

Fi s. 1 and 2 show the arrangement to con- 13101516 movement of thecylinders -d-dwhich .are revolved by means of a small electric motor notshown in the drawings; in any case, d must run slightlyquicker than -d.The power of the electric mo tor is transmitted direct to the cylinder dthrough the gear 'k -d receives its motion'through a belt embracing thepulley l; the shaft l carries at one end a plate owith a stopper --0 .incombination with a rod g which forms a part of the armature of a coil 14and is further controlled by a spring q so that. when the plate 0 turnsthe stopper 0 strikes the rod -g and this stops the revolving motion ofsaid plate but it does not stop the motor, as the belt slides onthepulley. Cylinder d does not revolve again till the coil 14- attractsthe rod qand gets it rid of the stopper -0 The shaft 3- of the cylinderd is fitted at one end with a plate 0 of non conductive material havinga metal tongue v in contact with the shaft 3. In front of the plate 0there is a brush 4: incontact with the surface of the plate. At the sametime, the surface of the cylinder -(P, which is not conductive, carriesa metal ring f embracing almost the whole circumference, and a platewhich corresponds to the interruption of the ring; this ring'combineswith wires "8-9' and the 0, becomes free, and the cylinder d ..11 5

goes on its revolvin movement. When the current is broken, t e rodqunder the action of the spring -q is placed again in the path of thestop 0".

For transmitting photographs there is produced in the sending apparatusa current -Z'n'i6 which is transferred by waves or by wires to thereceiving apparatus wherein a current -12-1110i '9-f-8- 7--. isgenerated. H
